No, I acutally dont think that we will see a loss of content.
Different marketing models: Yes.
Loss of content: No.
As I stated before: The same got declared when copying machines got cheap. The same was stated for software after P2P-networks became widely used, etc (Oh and btw: Printing was accused of the same stuff, too). It has not happened so far.

But neither a loss of content, nor a loss of copyright or similar. Heck, it didn't even happen for music or videos.

Different marketing models: Yes. Different players: Yes. Definitely more "community generated content", but there is still a very big market for professional writers (componists, etc) out there ...

But I agree - if the question would really be "secure DRM" or "loss of content" - it would be the loss of content, because there never will be (in fact there cannot be) a secure DRM system. At least non that can be used.
Because ... the only systems that could work would mean giving up ALL freedom - every single human right.
Business cannot just put a new "safe" DRM system onto society - they will have to cope with the changes, change their business models, make it easier to buy a book than to copy it, etc etc etc

Oh well, no one of us really can say what will happen, so I guess we will just have to see.
